General
NOTE
All plumbing work must be performed by a qualied technician. Always follow all local, state and provincial
codes.
A proper installation requires a pressure relief valve, a ¼" female N.P.T. threaded tting for the pressure sensor,
and properly sized pipe. Piping should be no smaller than the pump discharge and/or suction connections.
Piping should be kept as short as possible. Avoid the use of unnecessary ttings to minimize friction losses.
Some pump and motor combinations supplied with this system can create dangerous pressure.
Select pipe and ttings according to your pipe suppliers’ recommendation. Consult local codes for
piping requirements in your area.
All joints must be airtight. Use Teon tape or another type of pipe sealant to seal threaded connections. Use
caution when using thread sealant as any excess that gets inside the pipe may plug the pressure sensor.
Galvanized ttings or pipe should never be connected directly to the stainless steel discharge head or casing as
galvanic corrosion may occur. Barb type connectors should always be double clamped.

Pressure Tank, Pressure Relief Valve and Discharge Piping
Use only “pre-charged” tanks on this system. Do not use galvanized tanks. Select an area that is always above
34º F (1.1º C) in which to install the tank, pressure sensor and pressure relief valve. If this is an area where a water
leak or pressure relief valve blow-off may damage property, connect a drain line to the pressure relief valve. Run
the drain line from the pressure relief valve to a suitable drain or to an area where water will not damage
property.
Pressure Tank, System Pressure
Sizing – A diaphragm tank (not included) is used to cushion the pressure system during start-up and shut-down.
It should be sized to at least 20% of the total capacity of your pump. Example: If your pump is sized for 100 GPM
then size your tank for at least 20 gal. total volume, not draw down. Pre-charge your bladder tank to 15-20 PSI
below your system pressure. The controller is pre-set for 50 PSI at the factory. Therefore a 35-40 PSI pre-charge in
your tank would be required. Use the higher tank pre-charge setting if the system drifts over 5 PSI at a constant
ow rate. NOTE: Pre-charge your tank before lling with water!
CAUTION
Maximum working pressure of HydroPro diaphragm tank is 125 psi.
Installing the Pressure Sensor
The pressure sensor requires a ¼" FNPT tting for installation. Install the pressure sensor with the electrical
connector pointing up to avoid clogging the pressure port with debris. Install the pressure sensor in a straight
run of pipe away from elbows or turbulence. For optimum pressure control install the pressure sensor in the
same straight run of pipe as the pressure tank. Ensure the pressure sensor is within 10 feet of the pressure tank.
Installing the pressure sensor far away from the pressure tank may result in pressure oscillations. Do not install
the pressure sensor in a location where freezing can occur. A frozen pipe can cause damage to the pressure
sensor.
The pressure sensor cable is 30' as standard. The cable can be shortened for a cleaner installation. Longer cable
lengths are available, consult factory. Maximum recommended pressure sensor cable length is 300 feet. Avoid
leaving a coil of pressure sensor cable as this can induce unwanted transient voltages and noise into the system.
Do not run the pressure sensor cable alongside the input or output wiring. Maintain a distance of at least 8”
between the pressure sensor cable and input or output wiring.
WARNING
Discharge pressure within the piping system prior to removing pressure transducer or disconnecting any part
of the piping system. Open a valve until pressure on an external gauge reads 0 psi.

Section 3
3.1 Hardware Congurations
The HYDROVAR variable speed drive consists of two separate components: the power unit and the control card.
In its basic conguration (consisting of only the power unit) the HYDROVAR can be used as a Basic Inverter. In
that conguration the HYDROVAR can be used as a sequence pump in a multi pump system, or as a simple soft
starter for single pump applications.
By extending this Basic controller with the additional control card, the HYDROVAR is able to work in different
modes and can be used for multipump applications.
Three types of drives are available. They are each capable of different levels of control. They are:
Master controller:
• Full variable speed controller of itself in a single pump conguration, with more features than the Single
controller
• Full variable speed control of the attached motor and up to 7 additional Master or Basic controllers.
• Full variable speed control of the attached motor and on/off, xed speed control of up to 5 additional pumps.
(This requires an additional relay card.)
Basic controller:
• Single pump soft start control
• Full variable speed control when connected to a Master controller
Single controller:
• Full variable speed control of a single pump with fewer features than the Master controller
3.2 Modes of Operation
3.2.1 Actuator (for single pump operation only!)
In this mode the HYDROVAR operates as an actuator with external speed signal or switching between 2
programmed frequencies by using the corresponding digital input. For this application the HYDROVAR
operates like a standard frequency converter when an external controller is used.
NOTE
This mode can only be programmed with a Master or Single controller, and is for single pump systems
only.
3.2.2 Controller
This mode should be selected if only one HYDROVAR pump is in operation and there is no connection to
any other HYDROVAR via RS485 interface.
→ Typical single pump operation
3.2.3 Cascade Relay
One pump is tted with a HYDROVAR Master controller and up to 5 xed speed pumps can be switched ON
and OFF on demand. For this purpose an additional Relay Card with 5 relays is used in the Master controller.
Separate motor starters are needed for each motor relay, because the relays in the HYDROVAR are control
contacts only.
Lead/Lag switching of the xed speed pumps to provide even wear and achieve even operating hours can
be programmed in this mode.
This conguration is a cost effective alternative compared with other solutions using VFD’s on each pump,
but additional equipment is required, and you only have xed speed control of the pumps.
PRODUCT OVERVIEW

8
Application Example
Booster sets up to 6 pumps where only one pump is speed controlled by the HYDROVAR and the others are
xed speed (1 HYDROVAR Master Inverter+5 xed speed). This should be the standard conguration when
the additional Relay Card is used.
3.2.4 Cascade Serial and Cascade Synchron
In these modes each of the pumps is equipped with a HYDROVAR unit. All units are connected and
communicate via the RS485 interface.
At least one Master controller is used. The other pumps can be controlled by Basic or Master drives. The
Master controller continually reads the status and failures of the Basic controllers. All failures are indicated on
the master unit, including the date and time.
The Master controller has complete control of all pumps in the system, including automatic alternation of the
lead and lag pumps, which provides even wear and achieves even operating hours for each pump.
If the control card of a Master controller fails, each of the Basic controllers can be manually started by an
external switch (manual operation) for “emergency operation” of the system.
Application Example
Each pump, (up to 8 pumps), is equipped with a HYDROVAR unit. At least one Master controller will be
connected to up to seven Basic controllers. All units are connected via the serial interface (RS485).
The combination of the different HYDROVAR units that are used in a multi-pump-system depends on the
system requirements (i.e. in a 6 pump system 2 or more Master controllers can be used to increase reliability,
and up to 4 Basic controllers
without control card.
Minimum requirement: 1
Master controller and the other
pumps equipped with Basic
controllers.
PRODUCT OVERVIEW

9
To increase the reliability of a system, (in the event of a Master controller failure) a second Master controller
can be used.
Full-featured possibility: Each pump is equipped with a Master controller.
In this mode it is possible to run all pumps in cascade serial mode and synchronous mode as well.
This conguration allows each pump to become the lead pump. This also ensures a proper operation if one
Master controller fails. In this case another HYDROVAR takes control. This ensures that the operating hours of
each pump will be the same to ensure even wear of the pumps.
